IDM HD1080P Multi-E1 HD Video Codec Transmission Equipment

The IDM HD1080P Multi-E1 HD Video Codec Transmission Equipment provides bidirectional HD video (1920x1080P 60fps) transmission over 2 to 4 E1 links. When 3 or 4 E1 links are used, it can also provide one Ethernet transmission interface simultaneously.
With 2 E1 links, the 1080P 60fps format can be transmitted smoothly; with 3 E1 links, the image quality is nearly identical to the original. The transmission delay from encoding input to decoding output is less than 100ms. The Ethernet interface on the equipment can be used as a configuration monitoring interface, a soft encoding/decoding interface, or a transmission interface.
This equipment can also be simplified for unidirectional HD audio/video transmission.
